Lever route

Public UFO key lever checklist

The route below combines the community wiki and several current guide pages. Use it as a quick checklist, not as a permanent fact: Roblox simulator updates can move maze logic.

Reported order

Blue, red, green, reset, purple

Public route notes commonly start with the blue lever in the North East Maze, continue through red and green lever states, then use purple and additional red/green toggles before the UFO Key appears.

Reward check

Alien route and investor bonus

Multiple guides describe the key as a path to an alien interaction. When you verify the route, capture the exact reward text so this page can replace source notes with owned proof.

Page advantage

How this page can beat thin results

A generic article only says where a key is. A better guide gives route order, prompt screenshots, common wrong turns, and the exact update date. Add your first gameplay captures here before expanding into more Roblox games.

  • Capture the UFO gate prompt before opening other tabs.
  • Capture sewer entrance prompts and label them as tested or untested.
  • Keep outdated route notes visible but marked as old after updates.
